Best ResponseYou've already chosen the best response.1the magnetic flux change is: \[\large \Delta \Phi = \left( {0.2  0} \right) \times 0.12 = ...Weber\]

Best ResponseYou've already chosen the best response.1no, since the magnitude of the requested emf is given by the subsequent formula: \[\large E = \frac{{\Delta \Phi }}{{\Delta t}} = \frac{{0.024}}{{0.3}} = ...volts\]
